Analysis of Quantum Radar Cross-Section by Canonical Quantization Method (Full Quantum Theory)

open access: yesIEEE Access, 2020
This article investigates the difference between two quantum-based theories to calculate the radar cross-section (RCS). Quantum radar cross-section (QRCS) has been commonly analyzed using the dipole approximation method, and the related results show that

Wideband RCS reduction due to plasma generated by radioactive nuclei for cylindrical object

open access: yesScientific Reports, 2022
Radar cross section reduction has been one of the most important research topics in recent years. Plasma-based stealth is a method of reducing the radar cross section, which dampens the electromagnetic waves and reduces the amount of return waves.

Monopole Antenna Radar Cross Section Reduction with Plasma Helix [PDF]

open access: yesJournal of Electrical and Computer Engineering Innovations, 2017
In this paper, a new method for radar cross section reduction of a monopole antenna is proposed. In this method, a plasma helix like fluorescent bulbs is placed around the antenna element. The selected plasma parameter for this medium acts as an absorber
